If you get a copy of "Programmers Reference Manual" from motorola, it has 
the format for all opcodes together with the description of the instruction.
Get that book, it is very valuable for programming 68k. (I myself have hard 
to understand how people can manage to program for the processor, _without_ 
any manual like this one :)
At least before, you could order it free from motorola, but there is .pdf 
versions too.
The fastest way to find it is to download it from my page, 
http://alh.dhs.org/ti89/ , but you can find it on motorolas pages too.
